The coupling Inemberis preferably formed in two like sections by dividing the same longitudinally. By so constructing the same the passages are more easily formed and after use cleaned.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

Apipe stem, comprising a detachable coupling member having a tubular nipple, a centrai passage leading from the nipple, lateral openings in its rear portion and a supporting teat beyond the lateral openings, a casing on the coupling member, an absorbent cylindrical tube removably sleeved on the teat having its forward end closed by the teat WILLIAM J.
